Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a barrier-free auxiliary device for rail transit platforms. Background Technology

[0002] With the rapid development of urban rail transit, barrier-free travel has become an important indicator for measuring the level of urban transportation services. At present, most rail transit platforms are built to keep the platform floor level with the train car floor as much as possible. However, due to the design differences of different train models, there will still be a height difference between the platform and the car. For wheelchair passengers, parents with strollers or elderly people with mobility difficulties, this height difference will bring great travel obstacles.

[0003] Existing accessibility assistive devices mostly consist of fixed ramps or manually folding ramps. Fixed ramps require a large pushing force for wheelchairs to go up and down and are prone to slipping, resulting in poor safety. Manually folding ramps require manual unfolding and folding, which is cumbersome and fails to meet the needs for efficient, convenient and safe accessibility.

[0004] Therefore, a barrier-free auxiliary device for rail transit platforms is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a barrier-free assistive device for rail transit platforms, which can solve the problems that existing barrier-free assistive devices mostly involve laying fixed ramps or setting manually folding pedals. Fixed ramps require a large pushing force when wheelchairs go up and down, and are prone to slipping, resulting in poor safety. Manually folding pedals require manual unfolding and storage, which is cumbersome to operate, and thus cannot meet the needs of efficient, convenient and safe barrier-free travel.

The tops of the four transmission rods extend through to the top of the housing and are fixedly connected to a lifting platform. A drive assembly is provided on the right side of the lead screw.

[0008] Preferably, the protective mechanism includes a first guardrail and a second guardrail, the first guardrail being fixedly connected to the left side of the top of the lifting platform, and the second guardrail being fixedly connected to the right side of the top of the lifting platform.

[0009] Preferably, a fixing block is fixedly connected to the front and rear sides of the left side of the first guardrail, and a rotary motor is fixedly connected to the opposite side of the two fixing blocks.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A barrier-free auxiliary device for rail transit platforms includes a housing 1, a lifting mechanism 2 is provided in the inner cavity of the housing 1, and a protective mechanism 3 is provided on the top of the lifting mechanism 2.

[0028] The lifting mechanism 2 includes a lead screw 21, which is disposed in the inner cavity of the housing 1. The top and bottom of the surface of the lead screw 21 are rotatably connected to the inner wall of the housing 1 via bearings. The surface of the lead screw 21 is threaded with an internal thread lifting plate 22. The front and rear sides of the internal thread lifting plate 22 are fixedly connected with transmission plates 23. The top sides of the two transmission plates 23 are fixedly connected with transmission rods 24. The tops of the four transmission rods 24 extend through to the top of the housing 1 and are fixedly connected with a lifting platform 25. A drive assembly 26 is disposed on the right side of the lead screw 21.

[0029] In this embodiment: by setting up a housing 1, a lifting mechanism 2, and a protective mechanism 3, the housing 1 provides a supporting foundation for the lifting mechanism 2 and the protective components, and also provides a protective barrier for the lifting mechanism 2. The lifting mechanism 2 can stably support and assist people with mobility impairments, wheelchair users, and other special groups to complete the lifting transition between the platform and the train carriage, allowing them to cross height differences without relying on others, thus ensuring the convenience of independent travel for special groups. The protective mechanism 3 can effectively prevent people with mobility impairments or wheelchairs from sliding, tipping over, or falling during passage and lifting, thereby ensuring safe passage.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the protective mechanism includes a first guardrail 31 and a second guardrail 32. The first guardrail 31 is fixedly connected to the left side of the top of the lifting platform 25, and the second guardrail 32 is fixedly connected to the right side of the top of the lifting platform 25.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a fixing block 33 is fixedly connected to the front and rear sides of the left side of the first guardrail 31. A rotary motor 34 is fixedly connected to the opposite side of the two fixing blocks 33. The output shafts of the two rotary motors 34 pass through the two fixing blocks 33 and are fixedly connected to the protective baffles 35. The surface of the output shaft of the rotary motor 34 is rotatably connected to the inner wall of the fixing block 33 through a bearing.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the front and rear sides of the top of the second guardrail 32 are fixedly connected to a controller 4 that works with the drive assembly 26 and the rotary motor 34. The top of the controller 4 is equipped with a control button 5.

[0033] In this embodiment, by setting up a first guardrail 31, a second guardrail 32, a fixing block 33, a rotary motor 34, a protective baffle 35, a controller 4, and a control button 5, during the lifting process, the controller 4 can operate the top control button 5 to start the two rotary motors 34, so that the output shafts of the two rotary motors 34 drive the two protective baffles 35 to rotate, so that the two protective baffles 35 rotate to a horizontal protective position. At this time, the first guardrail 31, the second guardrail 32, and the two horizontally positioned protective baffles 35 can form an all-round protective barrier, which can effectively prevent people with mobility impairments or wheelchairs from sliding, tipping over, or falling during passage and lifting, thus ensuring safe passage.

[0034] Specifically, such as Figure 2 , Figure 3, Figure 5 As shown, the drive assembly 26 includes a fixed frame 261. The bottom of the fixed frame 261 is fixedly connected to the bottom of the inner wall of the housing 1. A drive motor 262 is fixedly connected to the top of the fixed frame 261. The output shaft of the drive motor 262 passes through the inner side of the fixed frame 261 and is fixedly connected to a drive gear 263. The surface of the output shaft of the drive motor 262 is rotatably connected to the inner wall of the fixed frame 261 through a bearing.

[0035] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, a driven gear 264 is meshed on the left side of the drive gear 263, and the driven gear 264 is fixedly connected to the bottom of the surface of the lead screw 21.

[0036] In this embodiment: by setting a fixed frame 261, a drive motor 262, a drive gear 263, and a driven gear 264, in use, by starting the drive motor 262, the output shaft of the drive motor 262 drives the drive gear 263 to rotate. The drive gear 263 will drive the driven gear 264, which is meshed with it, to rotate. The driven gear 264 will drive the lead screw 21 to rotate. Through the rotation of the lead screw 21, the internal thread lifting plate 22 can be lifted and moved by the thread.

[0037] Specifically, such as Figure 6 As shown, the front and rear sides of the top of the box 1 are provided with through holes 6, which are used to cooperate with four transmission rods 24 respectively. The surface of the transmission rod 24 is slidably connected to the inner wall of the through hole 6.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a rubber anti-slip pad 7 is fixedly connected to the top of the lifting platform 25, and the top of the rubber anti-slip pad 7 is provided with anti-slip texture.

[0039] In this embodiment: by setting the perforation 6, the transmission rod 24 can pass through the housing 1 to slide up and down. By setting the rubber anti-slip pad 7, the anti-slip performance of the lifting platform 25 can be improved.

[0040] Working principle: In use, firstly, an installation pit matching the size of the device is excavated in the platform ground. Then, the device is embedded and installed in the pre-set installation pit in the platform, with the initial state of the lifting platform 25 flush with the platform ground. When people with disabilities, wheelchair users, or other special needs need to cross the height difference between the platform and the train car, the user first reaches the lifting platform 25 flush with the platform ground. Then, the user can operate the control button 5 on the top of the controller 4 to start the two rotary motors 34, so that the output shafts of the two rotary motors 34 drive the two protective baffles 35 respectively. Rotation causes the two protective baffles 35 to rotate to a lateral protective configuration. At this point, the first guardrail 31, the second guardrail 32, and the two lateral protective baffles 35 form an all-around protective barrier, effectively preventing people with mobility impairments or wheelchairs from slipping, tipping over, or falling during passage and lifting, thus ensuring safe passage. During lifting operations, the drive motor 262 can be started via the control button 5 on the top of the controller 4. This causes the output shaft of the drive motor 262 to drive the drive gear 263 to rotate, which in turn engages with the gear. The driven gear 264 rotates, which in turn drives the lead screw 21 to rotate. Due to the threaded transmission effect, the internally threaded lifting plate 22, connected by threads to its surface, moves smoothly upwards along the axis of the lead screw 21. The internally threaded lifting plate 22 then drives two transmission plates 23 to move upwards, and through the transmission rods 24 fixed on both sides of the top, it raises the lifting platform 25 on top of the housing 1. The user can adjust the height of the lifting platform 25 in real time using the control button 5 until it is flush with the train car floor. After the lifting platform 25 is flush with the train car floor... By using the control button 5 on the controller 4 to start the rotary motor 34, the protective baffle 35 is reset and the protective mode is canceled. Then, the user can smoothly enter the train from the lifting platform 25. Then, by operating the control button 5, the drive motor 262 is turned in reverse, and the lifting platform 25 is driven back to the initial position through the above transmission path, thus completing one barrier-free passage operation. This enables people with mobility impairments, wheelchair users, and other special groups to complete the lifting transition between the platform and the train carriage. They can cross height difference obstacles without relying on the assistance of others, ensuring the convenience of independent travel for special groups.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
